YARN-WINDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 750,964, dated February2, 1904.

Application filed May 13, 1902- Serial No. 107,100. (No model.)

To ail whom it may concern:

Be it known that I, HENRY STAFFORD GoL- LAND, merchant, asubject of theKing of Great Britain and Ireland, residing at The Gables, Broad OakPark, Worsley, in the county of Lancaster, England, have inventedcertain new and useful Improvements in Yarn-Winding Machines, (for whichI have made application in Great Britain, No. 21,788, dated October 30,1901,) of which the following is a specification.

This invention relates to yarn-winding machines for cross-winding singleor multiple threads into cops, and has reference to improvements inmachinery for which Letters Patent No. 586,279, of 1897, No. 605,98 1,of 1898, and N 0. 641,420, of 1900, have been granted to John DempsterWhyte.

In constructing a machine in accordance with my invention I employvertical spindles, which are lowered as the winding proceeds, andyarn-guides vibrated by cone-cams, as described in the specifications ofthe above patents, to which I refer the reader for particulars as toconstruction and method of operation.

My invention relates, essentially, to the means for driving thecone-cams and spindles and lowering the spindle-carriageand to animproved stop-motion for stopping the revo- 7 lution of the cone-camsand spindles and for arresting the downward movement of thespindle-carriage. To attain success, it is of the highest importancethat stopping and starting of all these moving parts should abso lutelysynchronize; otherwise it is impossible to produce Well-formed cops.

The following description and accompanying drawings relate to onespindle only, it being understood that a frame could be provided withany desired number of spindles arranged at both sides of the frame or atone side only, the method of working being the same for all thespindles.

In the drawings, Figure 1 shows an end View of a winding-frame toindicate the method of driving the cone-cams and spindles and counprovedmethod ofdriving the cone-cams and spindles and for lowering thespindle-carriage and the stop-motion therefor. Fig. 1 is a frontelevation thereof. Fig. 5 is a plan with some of the upper partsremoved, and Fig. 6 a detail view.

Referring in the first place to Figs. 1 and 2,

the winding-frame is provided with a main driving-shaft a, having fastand loose pulleys b 0, respectively, power being obtained from anysuitable source. For starting and stopping the machine a belt-shiftingfork d is provided, which is slid on a bar 6 by means of a crank f andconnecting-rod g, operated by a handle it from either end of across-shaft 2'. Counter-shafts 7' are mounted in suitable bearings onopposite sides of the main drivingshaft (0. These counter-shafts aredriven at a reduced speed by means of a gear-wheelie, mounted on thedriving-shaft a. The gearwheelk meshes on one side (the right of Fig. 1)with a gear-wheel Z and on the opposite side with a gear-Wheel 0, whichin its turn meshes with a second and similar wheel Z. ()n the shafts ofthe wheels Z are gear or spur wheels m, which mesh with the spur-wheelsn on the counter-shafts j. To secure uniformity in the direction ofrotation of the side shafts a carrier-pinion 0 is provided at one sideof the main driving-shaft a. The spurwheelsZ Z are made changeable tovary, as desired, the speed of the side shafts j, according to thevarying counts of yarn being wound into cops.

Having explained the method of driving the side shafts j from the maindriving-shaft a, I will now refer to Figs. 3 to 5. The driving of thecone cam pulley p and the slidable wh arve of ,the spindle q is effectedby means of bandsr s, respectively, from adouble-grooved pulley t,mounted loosely on the shaft a. To regulate the tension of the band 8, Iprovide a bracket A, carrying a pulley B, which may be raised orlowered, as required, in the slot abutment on the shaft a. The method ofdisengaging the pulley t from the friction-disk a will be describedlater. To efiect the requisite slow downward movement of thespindle-carriage y to obtain the building of the cops, I provide awormz, mounted loosely on the shaft 1'. To drive the worm, it is formedwith a friction-nut 1, which is driven by a friction-disk 2, slidablymounted on the shaft and driven thereby by a feather or the like. Thefriction-disk 2 is thrust into engagement by means of a spring 3,confined between a collar 4, carried by the slidable friction-disk 2,and a fixed collar 5 on the shaft 1'. The worm 2 gears with a worm-Wheel6, carried on the top of a screwed spindle 7, which is mounted torevolve in suitable bearings in the frame of the machine. To the bottomor any other suitable part of the spindle-carriage y I secure a housing8, carrying spindle 9, having at its protruding end a half-nut 10,engaging with the screwed spindle 7. The half-nut is thrust into gearwith the screw-threaded spindle by means of a spring 11. It will beapparent that as the screw-threaded spindle is revolved by theworm-gearing in the required direction the spindle-carriage will beslowly lowered. An essentially important feature in this arrangement ofmeans for lowering the spindle-carriage is that the worm-gearing andscrewthreaded spindle and nut positively lock the spindle-carriage, sothat on the stoppage of the worm .2 the spindle-carriage remainsimmovable. By these means the winding must necessarily be alwaysrecommenccd at the exact point on the spindle where it left off.Irregular winding of cops is therefore obviated.

I will now describe the means for simultaneously stopping thedrivingpulley t and worm 2, whereby the stoppage of the conecam,spindle, and spindle-carriage are synchronized.

Embracing an annular groove 12, formed in the boss of the doubledriving-pulley t, and a similar groove 13 of the slidable frictiondisk2are forks 14 and 15, respectively. These forks are formed withoppositely-arranged inclines or cam-surfaces 16. The forks 14 and 15 aresecured to each end of a rod 17, which is capable of sliding in bearings18, carried by a bracket 19. A strong spiral spring is secured at oneend to an extension 21 of the fork 14, the other end of the spring beingsecured to the bracket 19 at 22. When the forks 14 and 15 are in theposition shown in Fig. 5 and the clutches on the shafts a and j areengaged, the spring 20 is in tension. To maintain the forks in thisposition, one of them (see Fig. 3) is provided with a tooth or abutment23, bearing against a corresponding tooth 24, carried by a detent-lever25, which is pivoted at 26 to a pillar 27 secured to or formed on thebracket 19. When the detent-lever is raised, the strong spiral springimmediately slides the rod 17 in the direction of the arrow, Figs. 3 and5. The inclines 16 on the forks l4-and 15 then act as wedges andsimultaneously force out of gear the drivingpulley t,with thefriction-disk a, and the slidable driving friction-disk 2, with the wormfriction-disk 1, thus bringing about the synchronous stoppage of thepulley t and worm z and cessation from motion of the cone-cam pulley p,spindle q, and spindle-carriage y. This raising of the detent-lever iseffected on the breakage of a thread in the following manner: Thedetent-lever is connected, by means of a rod 28, to a lever 29, which ismounted on a pin 30, carried eccentrically on the cone-camdriving-pulley p. The other end of the lever 29 is formed with a slot 31and is suspended from a pin 32, carried by a crank 33. The crank ismounted on a spindle 34, provided with a cam 35, arranged in a catch-box36. This catch-box is in itself not novel and is provided, as usual,with a slot 37, having a number of looped needles 38 held suspended bythe yarns being wound. Normally the eccentrically mounted lever 29causes the crank 33 to oscillate, as indicated in the dotted lines inFig. 3, the cam 35 also rock-' ingbelow the suspended needles 38. Thelower end of the rod 28 is allowed a little free play, so that anymovement imparted to the rod 28 by the oscillation of the lever 29 willnot affect the detent-lever 25. On the breakage of a thread, however,the needle previously held up thereby falls in the slot 37 and offers abarrier to the oscillation of the cam 35, which also locks the crank 33.The lever 29 thus being unable to rock the crank 33 rides upward on thepin 32, the slot 31 permitting this, the upward movement of the leverraising also the rod 28 and lifting the detent-lever 25 out ofengagement with the abutment 23 and enabling the clutches to bedisengaged by the spring 20, as described.

In the drawings four threads are being wound on the spindle; but it willbe understood that this number may be varied from one to any practicablenumber.

In order to secure a long end on the breakage of a thread to facilitatepiecing, the cops 39 are mounted on a side rod or rail 40, and thethreads are passed through antiballooning eyes 41, carried by a board42, then over a tension-board 43, through the needles 38 in thecatch-box, around a pulley or glass rod 44, through eyes 45, and fromthence to the yarn-guide 46. (See Fig. 1.) This method, however, formsno essential feature of my invention and may be varied. To restartwinding after piecing up has been effected, I provide a pivotedtreadle-plate 47, to which is secured a rod 48, connected to abell-crank lever 49. The other arm of the bell-crank lever is connectedto a rod 50, which is also secured to a bracket 51, fixed to the slidingrod 17. By depressing the treadle-plate 47 the parts are returned to thepositions shown in Figs. 8 to 5. I also provide means for automaticallystopping the winding on a predetermined length of cop being attained.

The copping-plate 52 (see Fig. 6) is, as usual, provided with a slot 53,within which works the pin 54 of the bell-crank lever, which actuatesthe bowl 55 of the yarn-guide 46. The curved portion of the slot 53serves to gradually shift the bowl 55 of the yarn-guide from thesmallest diameter of the cone-cam 56 to the largest diameter, asexplained in the specifications of the said former patents, No. 586,279,of 1897, andNo. 605,984, of 1898. The pin 54 occupies the straightportion of the slot 53 after the cop-bottom has been formed, as will beunderstood, the length of the slot being equal to the maximum length ofthe cops required.

To stop the apparatus when the desired length of cops has been attained,I provide an adjustable clip 57, having a pin 58, and I secure anextension 59 on the crank-pin 32. (See Fig. The extension 59 comes intocontact with the pin 58 when the copping-plate 52 has been loweredsufficiently to form the desired length of cop and the oscillation ofthe crank 83 is arrested, so as to bring the stopmotion into action inthe manner already described.

To raise the spindle-carriage to commence the winding of another cop,the half-nut 10 is provided with a hooked handle 60, by means of whichthe half-nut can be withdrawn into the housing 8, compressing the spring11, and thus disengaging the nut from the screwthreaded spindle 7 andenabling the spindlecarriage to be returned to its initialstartingpoint.

Although I have particularly instanced the yarn-guide and means foroperating same described in the specifications of the said priorpatents, No. 586,279, of 1897, and No. 605,984,

of 1898, my improvements may be used with any suitable yarn-guide.

I declare that what I claim is" 1. In combination in a yarn-windingmachine, a vertically-movable spindle-carriage, a half-nut securedthereto, a screw-threaded spindle engaging said half-nut, meansfordisengaging the half-nut from the screw-spindle when desired,wormgearing for operating said spindle and stop mechanism whereby therotation of said screw threaded spindle is stopped on the breakage of athread and the spindle carriage positively locked against movement,substantially as described.

2. In a yarn-winding machine, the combination with the maindriving-shaft, a doublegrooved pulley loosely mounted thereon, ayarn-guide and a spindle operated from said double-grooved pulley, acounter-shaft driven from said main shaft, a vertical screw-threadedspindle, a spindle-carriage, a spring-pressed half-nut on thespindle-carriage engaging said spindle, with means for disengaging ittherefrom, operating connections between said screw-threaded spindle andthe counter-shaft, a clutch included in said connections, a clutch forclutching the-double-grooved pulley to the main shaft, connected slidingforks having inclines for operating both said clutches, a spring tendingto force said forks into position to disengage the clutches, a detentfor holding said forks normally inoperative, an oscillating lever foroperating said detent, and a catch-box for controlling the action ofsaid operating-lever, substantially as described.

In witness whereof I have hereunto set my hand in presence of twowitnesses.
